PROTECTOR-CAP FOR BURNERS.

Specification of Letters Patent.

Patented Sept. 25. 1906.

Application filed May 16,1906. Serial No. 317,215.

To all whmn it may concern.-

Be it known that I, CHARLES T. FULLER, a citizen of the United States,residing at Olean, in the county of Cattaraugus and State of New York,have invented certain new and useful Improvements in Protector-Caps forBurners; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to new and useful improvements in glassprotector-baskets for lamps, and comprises a cup made, preferably, ofopal glass and adapted to support a globe and so arranged that it willcatch any particles of carbon or fire that may drop from the burner andbeing transparent will avoid the throwing of shadows beneath the same.

The invention consists of various details of construction andcombinations and arrangements of parts, which will be hereinafter fullydescribed and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which 4Figure 1 is a sectional view through my invention. Fig. 2 is a detailperspective view of the protector-cup. Fig. 3 is a detail perspectiveview of the drum which fits over the Bunsen tube. Fig. 4 is aperspective view of the protector-cup-supporting shell, and Fig. 5 is atop plan view of the globe-supporting member.

Reference now being had to the details of the drawings by letter, Adesignates a Bunsen tube having an air-inlet A, and B is a shell havinga set-screw B, mounted in a threaded aperture in the wall thereof, saidscrew being adapted to bind against the Bunsen tube to hold said shellin an adjusted position. The shell B is provided with a shoulder Bhaving a series of apertures B formed therein, through which air isallowed to enter for ventilation purposes.

C designates the protector-cup, which is made, preferably, of opal glassand has its lower end contracted and adapted to rest upon said shoulderB The upper portion of the cup flares outwardly and is provided withseries of beads C, in which sockets are formed for the reception of thespider-arms J, which radiate from the band J.

D designates a burner-drum in which the Bunsen tube telescopes and whichdrum is adapted to receive the set-screw B, which passes through anaperture which is in registration with an aperture in the shell B. Saiddrum D has series of lugs D about its circumference, forming a means forsupporting the band J. Rising from said arms J are the resilient fingersI, which are adapted to engage the lower contracted end of the globe Hand hold the same securely in place.

When the parts are adjusted in place as shown and described, it will beobserved that the protector-cup will surround the parts intermediate theglobe and the burner-drum and afford means for catching any particles ofcarbon or other foreign matter which might fall from the burner andbeing made of opal glass will avoid the casting of shadows which isusually the case with opaque devices which may be utilized for thispurpose.

What I claim is- 1. In combination with a Bunsen tube, a shell and aburner-drum adj ustablyheld upon said tube, a transparent protectorsupported by said shell, lugs projecting from the drum, and aglobe-holder supported by said lugs, as set forth.

2. In combination with a Bunsen tube, a shell and a burner drumadjustably held upon said tube, a transparent protector supported bysaid shell, lugs projecting from said drum, a globe-holder supported bysaid lugs and having arms projecting therefrom, the ends of said armsengaging sockets formed in said protector-cup, as set forth.

3. In combination with a Bunsen tube, a shell and burner-drum securedthereto, said shell having a shouldered portion which is provided withvent-apertures, a transparent protector cup resting upon said shoulderwithin the shell, and a globe-support mounted upon said drum, as setforth.

4. In combination with a Bunsen tube, a
